Fossils: Life Cast in Ancient Stone
How can you turn a soft, organic, squishy organism into a fossil that can survive earthquakes, rising mountains, closing oceans, and colliding continents for millions, perhaps even billions, of years? Just what are the chances of some organism becoming a fossil? Learn about the necessary conditions required for a fossil to form and just how unlikely it is to happen. […]
